Feeding rod touch pressure sensor of plate-shaped workpiece hemming device

Abstract

A feeding rod touch pressure sensor of a plate-shaped workpiece edge wrapping device is composed of an inductance coil, an inner support and its built-in touch switch, an inner eddy current ring, an outer support and its built-in tact switch, and an outer eddy current ring. The inductance coil is a disc ring structure as a whole, which is wrapped around and fastened to the inner ring of the bearing inner ring at the bottom end of the feeding telescopic rod. The upper end of the inner bracket passes through the top wall of the feeding suction cup, and the upper top is tightly bonded to the bottom of the lower opening of the feeding connector along the left side, and the bottom end surface and the outer ring of the inner vortex ring and the inner ring of the outer vortex ring are on the left side Tight bonding, built-in touch pressure switch, the two terminals of the normally open contact of the switch are respectively connected with the two terminals of the inner eddy current ring fracture opening. The upper end of the outer bracket passes through the top wall of the feeding suction cup, and the upper top is tightly bonded to the right part of the bottom of the lower mouth of the feeding connector, and the bottom end surface and the inner ring of the outer vortex ring and the outer ring of the inner vortex ring are on the right side Tight bonding, built-in tact switch, the two terminals of the normally open contact of the switch are respectively connected with the two terminals of the broken opening of the outer eddy current ring.

Description

technical field [0001] The invention relates to a method for wrapping the side of a flat workpiece. Background technique [0002] In many production lines of flat-shaped products, there is a process of side-wrapping flat-shaped workpieces, especially for circuit board manufacturers. This type of production process is: wrapping the entire periphery of the flat-shaped workpiece with a special adhesive tape. At present, this kind of process is all done manually, and the result is that the consistency of the wrapping state is poor, and there are defects such as partial sticking, folds, and leaks in different parts. For the usual large and heavy boards, manual operation is more difficult. This is a bottleneck that seriously affects the process of related product production lines, hindering the automation of the entire production process. Therefore, it is urgent to develop an automatic method that can ensure the consistency of the wrapping state and replace the heavy manual ope...
